Hypoventilation may be caused by an uneven distribution of inspired air (as in bronchitis), obesity, neuromuscular or skeletal disease affecting the thorax, decreased response of the respiratory center to carbon dioxide, or a reduced amount of functional lung tissue, as in atelectasis, emphysema, and pleural effusion.
Seborrheic Keratosis Causes Wart Like Skin Growths. Seborrheic keratosis causes wart like skin growths to appear on just about every body thatâs over age 40. Although they resemble skin cancer, these keratosis tumors are benign.
Warts can be surrounded by skin that is either lighter or darker. Warts are caused by different forms of Human Papilloma Virus (HPV). They occur in people of all ages and can spread from person to person and from one part of the body to another. Warts are benign (noncancerous) and generally painless.
